Question

question 1
which encompasses a larger area?
s - wave shadow zone
p - wave shadow zone

Explanation:

S - waves (transverse waves) cannot travel through liquid. The outer core is liquid. So the S - wave shadow zone is created on the side of the Earth opposite to the earthquake focus where S - waves are not detected. P - waves (longitudinal waves) can travel through both solid and liquid, but they refract when entering the outer core. The P - wave shadow zone is smaller than the S - wave shadow zone because P - waves can at least partially penetrate the outer core (even though they refract), while S - waves are completely blocked from a larger area due to the liquid outer core.

Answer:

S - wave shadow zone
